To all whom it may concern.' l

Be it known that I, ALBERT B. KNIGHT, a citizen of the United Statesresiding at Fairmont, in the county of 7Marion and State of WestVirginia,have invented c'ertain new and-useful Imrovements in Machinesfor Burning or lazing the Edges and Sides of Glassware, of which'thefollow- :ing is a specification.

This invention relates to. new and useful improvements in machines forburning or glazing the edges and sides of glassware.

An important object ofthe invention is to provide means forsimultaneously glazing necessarily be of some length as the machine mustbe used for glazing very short tumblers as well as the long stemmed typeto be of any practical value. A

In my construction, instead of raising or lowering the spindlesthemselves, I have provided a carrier for the spindles which may beraised or lowered, thereby removing the thrust from the lower end of thespindle. 'Other objects and advantages lof my invention will be apparentdurlng the course of the following description. l

In the accompanying drawingsV forming` a part of this specification andin which like numerals are employed to designate like parts throughout'the same,

Figure 1 is a'side elevation of my machine, i

Fig. 2 is a section taken on line 2-2 of Fi 1 ig., 3 is a section takenon li-ne 3-3 of Fig. 2, p

Fig. 4 is a section taken on line 4 4 of Fig. 1,

Fig. 5 is a section taken on line 5-5 of Fig. 1,

Fig. 6 is a section taken on line 6-6 of Fig. 1,

Fig. 7 is a section taken on line 7-7 of Fig. 1,

Fig. 8 is a plan view of the drive for the machine,

ig. 9 is a front elevation of the burner, an d Fig; 10 is a sectiontaken on line 10-10 of F 4.

Re erring now more particularly to the drawings, the numeral 10indicates a suitable base upon which is mounted a socket ange 11, havinga socket 12 formed therein.

Seated in the socket 12 is a vertical shaft 13, -which is held againstrotation by a set screw 14.- or `the like. Seated upon the 'upvper endof the Vsocket flange 11 is' athrust bearing 15, upon which is'mounted asleeve 16, 'surrounding the shaft. The sleeve 16 is provided upon itslower end with an outstanding flange 17, to which is secured, by meansof bolts or the like, a sprocket gear 18. Secured to the base 10 is asupport 19, to the outer end of which is secured a vertical member 20having upper and lower brackets 21 and 22 secured thereto. Rota-4 tablymounted in journals formed in these brackets is a vertical shaft 23,provided upon its upper end with an operating handle 24. Adjacent itslower end, vthe shaft 23 is provided wxidthba sprocket gear 25,alinedwith the...spr.ocket gear 18 and connected thereto with a chain26. It will be readily seen that when the handle 24 is rotated, thesleeve 16 is rotated simultaneously therewith.

The sleeve 16 is provided upon its upper end with external screw-threads28. Mounted upon the up er end-of the sleeve 16 is an internally treaded sleeve 27, the internal threads of which engage with the externalthreads 28 of the sleeve 16. The upper end of the sleeve 27 has aninturned flange 29, having a central aperture adapted to receive thevertical shaft 13. Mountedl upon the flange 29 is a .thrust bearing 30,or its equivalent, upon which is in turn mounted a hub 31, having radialarms 32, which distend a gear 33.

Secured, upon the base 10 is a standard 34 embodying journals 35 and 36.Mounted in these journals is a vertical tubular member 37 to which issecured a gear 38. This gear, in the present instance, is shown ascomprising a worm gear which meshes with a worm 39 formed upon the shaftof a motor 40. 7The tubular member 37 is r0- vided with a vertical slot41, and provides at its upper end a bushing 42, forming a journal toreceive a shaft 43. The lower end of. the shaft 43 has an enlargedportion 44, having a'sliding fit with the interior of the tubular member37 and is provided upon this enlargement with a pin 4 5 engaging in thevertical slot 41. Adjacent its upper end, the shaft 43 is provided withspaced lianges 46 and 47. Secured to the sleeve-27 is a bracket 48,provided with an extension 49, adapted to receive the shaft 43 betweenthe ilanges 46 and 47. The shaft 43 is provided uponits upper end with apinion 50, meshing with the gear 33.

A bracket' 48 is secured to the sleeve 27 and this bracket is providedwith a plate 49, having an opening therein for the'reception of thesleeve 43, the plate 49 being adapted to be arranged` between theflanges 46 and 47. j

It will be readily seen that the bracket 48 and its extension 49,engaging the shaft 43, perform a two-fold purpose, the shaft 43, beingincapable of transverse movement,` prevents rotation of the sleeve 27and the sleeve 27, and its'bracketwhen raised or lowered by the rotationof the sleeve 16, will move the shaft 43 correspondingly. As thehub'ofthe gear 33 rests upon the upper end of the sleeve 27, it will bereadily seen that the pinion 50 is kept in permanent engagement with thegear 33 and rotation of the sleeve 37 transmitted to the gear 33 bymeans of pin 45, shaft 43 and pinion 50.

Secured to the upper face of the gear 33 by meansof bolts y51 or thelike, are a plurality of radial arms 52. These arms are provided u ontheir outer ends with substantially -shaped frames 53, `providing s acedjournals 55, affording a support for t e bottom of the spindle. Securedupon the spindle 56 intermediate the journals 54 and is a pinion57, thepurpose of which will hereina ter appear.

Mounted upon the upper end ofthe hub 31 of gear 33 1s a hub 58, rotationofthe hub 58 beinsnr prevented by means of screws 59,

' or the h e engaging in key-ways 60, formed in am sima 13. The hub 5sis pmvideawith radial arms 61, distending a gear 62, meshing with thepinions 57 secured to the spinj dles 56.

iAt spaced intervals, as for example, at Aintervals of ninety degrees, Iprefer to provide rollers 63, secured to the spindle journals 54. Theserollers rest upon the upper face of the gear 62, and have a tendency torelieve the torque upon the gear 33, placing a ori tion of the Weightupon the gear 62. he spindles 56 are provided upon their upper ends withthe usual sockets 64, adapted to receive the base of the tumbler to beglazed.

Secured to the upper end of the shaft 13 by means of a flanged bracketis a support 66. Secured to the support 66 inany and that the openings70 are arranged u on a curved line. The casing 68 is connecte bymeans ofconduits 71 with a suitable source of combustible fuel supply 72.Secured upon the upper peripheral edge of the casing 68 is a receptacle73 having a filler 74 composed of refractory material, such as fireclay. It will be seen by'examining Fig. 2, that the openings 69 direct ajet of flame against the lire clay and the heat of the flame isreflected downwardly upon the edge of the tumbler. The fire clay isformed tapered outwardly so that the hottest rtion of the flame isspacedv as far as feaslble from the upper edges of the tumbler andtheouter edge of the flame is brought as close as feasible to the tumbler.The purpose of this tapered construction is to apply to the upper ed eof the glassware a uniform heat.

'he operation of m device is as follows:

The tumblers are p aced in the sockets 64 of the spindles 56 and raisedor lowered by rotating the handle 24 until the tumblers are in .the proer spaced relation with the fire clay 74. he burner 67 is then ignitedand the motor started. The arms 52 being fixed upon the gear `33 arerotated therewith and as the gear 62 is fixed against rotation,

the spindles 56 are rotated through the mea dium of the pinion 57meshing with the gear 62. It will be seen that the tumblers aresimultaneously advanced and rotated. As the tumblers pass beneath thefire clay 74, the up r edges thereof are glazed by the flamev rectedfrom the openings 69. The sidesv of the tuinblers are simultaneouslyglazed by the staggered openings 70 and by reason of the peculiarconstruction of this row of openings, flame is directed to all parts ofthe outside of the'tumbler.V Y

It is` to be understood that the form of my invention herewithv shownand described is to be taken as a preferred example of the same, andthat various changes in the shape, size, and arrangement of parts mayberesorted to without departingfrom the spirit of my invention or thescope of the subjolned claims.
